This book has been long out of print and I found it on the web. I find it intriguing and as a man who has too many books, having them available on the web saves valuable space. The point of the book seems to be that ethics should be directed toward whatever is good for the evolution of man.

Now I say seems because in a work of this type to summarize the deep and thoughtful work required for a book in a single sentence is arrogant. So, I recommend you read the whole thing if you find these kinds of ideas interesting.
